I suggest he save his money or you add some money and buy him a Browning Citouri or an
Olin Kodensha Winchester 101.
My buddy Pete Feron that's 90 years old and brought back over 100 Winchester 101's when stationed in Japan in the 1960's when asked about his experiences with Mirouko said back in the early Mirouko days that they were prone to breaking and you couldn't give them away.

If you think you're nephew will be happy with a junk gun with gold painted birds then go with Stans suggestion.
